20 millions d’années ont permis la création des légendaires et mythiques montagnes de Djurdjura. Nées d’un désastre géologique, un désastre qui a soulevé des tonnes de croutes terrestres à des milliers de mètres d’altitude, donnant ainsi naissance à un paysage remarquable, un paysage qui a envouté des poètes et fait saliver des conquérants durant des milliers d’années                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 . Ses périodes glaciales en hiver ont formé des cocons naturels qui préservent et donnent à l’eau OVITALE sa composition unique et riche en minéraux.
